Speaking on the BBC’s Question Time programme, Liberal Democrat leader Ming Campbell said:
“I don’t think it is any longer right that the Prime Minister should have the opportunity and right to determine when elections should be held.
“What began as a tease has become an abuse of the political process. We shouldn’t have elections at the convenience of the PM, whose purpose is to advance the cause of a political party. It should be in the public interest.
“Nothing that has happened in the past few weeks has been in the public interest.”
